COMPOUND PRESS.

SPECIFICATION forming part of Letters Patent No. 435,212, dated August26, 1890.

Application filed February 18, 1890. Serial No. 340,956. (No model.)

press for compressing cotton, hay, &c., has

for its object to provide a press of this character, wherein the upperand lower platens are arranged to move simultaneously toward or fromeach other, whereby the travel of the lever-sweep or the piston isdiminished to one half the stroke of the press, thereby accelerating thespeed of the press and increasing the amount of work done in a giventime.

It has also for its object to provide a press of such a constructionwhereby the operation thereof will be simple, positive, and effectivefor its desired purpose.

To this end my invention consists in the novel arrangement and peculiarcombination of the several parts, all of which will hereinafter be fullydescribed in the annexed specification, and particularly pointed out inthe claims, reference being had to the accompanying drawings, in which-Figure 1 is a front elevation of my improved compound press, and Fig. 2is an end elevation of the same.

In the accompanying drawings, A denotes the bed-castings provided withdepending lugs to a, to which are centrally pivoted levers B, to theinner ends of which are pivoted the lower ends of the bars 0 O, theupper ends of which are pivoted centrally to the lower face of theplaten D, while to the outer ends of said levers B are pivoted the lowerends of the bars E, pivoted at their upper ends to the upper platen F,as shown, the lower ends of the bars 0 and E being pivoted at the samedistance from the pivotal axis of the levers B, so that the distance ofthe movement of.

the said bars 0 and E up or down will be the same.

G denotes the cross-head, which consists of end plates G G thecross-bars II, connecting said bars G G, and the tie-rod K. In theconstruction shown I provide the cross-bars H with lugs h h, which abutagainst the in,

lower platen.

ner faces of the inner plates G, and form said faces with inwardlyprojecting lateral apertured lugs g g, between which fit the aperturedends of the tie-rod, the latter being held to such lugs by the bolt 9 g,as most clearly shown in Fig. 1 of the drawings.

Idenotes the vertical bars, betweenwhich the ends of the platens areguided in their vertical movement, the upper ends of which are heldbetween the bifurcated ends 9 of the plates G G, and locked therebetweenfrom upward movement by the wedge-keys g g, which pass throughcoincident apertures g in the plates G, and the under faces of whichengage lugs t' 't' on the bars I, as shown, the lower ends of saidguides fitting in sockets j, formed in base-plates J J, secured upon thebed-plate A, such ends being also provided with lugs t" t", which engagethe lower edge of the wedge-keys g g, which pass through the horizontalapertures j j in the base-plates J J. By this construction it will beobserved that the guides for the platens can be quickly adjusted andfirmly held in position.

In the bifurcated ends of the plates G G, I pivotally secure the endsof. the brace-rods L L, the lower ends of which are pivoted between ears0 c on the outer ends of lateral extensions of the bed-plate A, asshown. The

lower platen consists of the base 10 and the removable faceplate 20,provided with a centrally-arranged depending lug 30, which projectsthrough a central aperture in the base 10 and is held thereto by the key40, as shown. The upper platen consists of a cross-head 50, having aface-plate 60 on its lower face, which is secured to the cross-head in amanner simi lar to the connection of the face-plate on the The ends ofthe cross-head extend beyond the guides I, such ends being formed intoapertured ears '70, to which the upper ends of the arms E E areconnected.

In the practical construction of my invention I weight the lower platento overbalance the upper platens, so as to cause them to recede fromeach other after the power for bringing them together is released. Ifdesired, the platens may be of the same weight and may be forced apartby any suitable lever-power.

Any desired means may be employed to apply the pressure to the platens;but I prefer to employ the hydraulic rams M M, as shown, which areoperated in the usual manner.

From the foregoing description, taken in connection with the drawings,it will be observed that while the construction of my pacity for work,the connections between the platens serving to provide astrongleveragepower equally distributed thereto. It will also beobserved that by connecting the short lever-arms C C centrally to thelower platen to push upward, and the long armsEEto the outer extensionsof the upper platen to pull downward, the pressure is not onlyequalized, but the arms serve to steady and guide all of the parts andhold the same from lateral movement.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. A compound press consisting of the supporting-frame, said frameformed of the bedcastings A, the cross-head G, the guides I,

and brace-rods L, arranged as shown, platens D I, held to slidevertically between said guides I, the ends of the upper platen extendedbeyond said guides, the centrally-pivcured at one end to the outer endsof the swinging levers B and at their opposite ends to the lateralextensions of the upper platen, and means for forcing the lower platenupward, substantially as shown and described, whereby the upper platenwill be drawn downward, as and for the purposes described. 2. In acompound press, the combination, with the supporting-frame, of theguides detachably held thereon, the platens D F, held to slidevertically between said guides, the lower platen formed of a heavierbody than the upper platen, whereby to overbalance the same, theconnections B O E intermediate said platens, whereby the upward movementof the lower platen will'force the upper platen downward, and suitablepower for forcing said lowerplaten upward, said lowerplaten adapted torecede when power-pressure is released, and thereby draw the upperplaten up, substantially as and for the purpose described.

3. A compound press comprising a supporting-frame consisting of thecasting A,

the cross-head G, the brace-rods L, connected to the cross-head and thebed-plate A, and the guides I, detachably secured at their upper ends tothe cross-head G and at their lower ends to the bed-plate A, the platensD F, held to slide vertically between said guides I, theintermediatedevices B C E, connecting said platens, whereby they are caused to movetoward or from each other, and means for raising the lower platen,substantially as shown and described.
